Sonos Can't Find Music Library (Computer Not Found)

I'm having a problem adding my music library to Sonos. I've sent diagnostics with confirmation number: 2324524. I have a desktop PC with itunes music. I have my sonos bridge connected directly to my router (no wireless). I have my PC connected directly to the router as well. From my desktop PC, I can open the sonos program and play all music - pandora, songza etc. But my library doesn't appear. When I try to add the library (which is on the desktop itself), I get the message indicating that my Computer is not found. This was working a month ago and not sure what has happened. Thoughts? Andy

Sounds like you have a problem with your setup that most of us don't have. If you contact Sonos support (this is a user to user forum) with a diagnostic number taken when you have the issue they can likely tell you what you need to do to fix things. Check the Contact page, many options, some open 24x7.

Sonos support does visit here but you tacked onto the bottom of a year dead topic so it may be missed and without a diagnostic there isn't much Sonos can do to help you.

Almost forgot do you have Sonos Ones or Play 1s, they are very different speakers with foolishly selected names.

Anybody interested in buy 2 used sonos 1? It looks great, you can use it to play tunein stations, ... mp3 files in your local drive... no, you can't use it for that.
Music Library is an ornament.
To make it work, uninstall sonos controller, reboot, install sonos controller, with luck, it will work. Play all the songs at once.
Do you want to hear music again?, easy: Uninstall, reboot, install... and so on

Maybe a little of KISS philosophy is needed in the software.


Interesting, my internet went out over the weekend. Was able to play my music library with no issues... I don't even have a supported OS for the desktop controller!

Clearly there is an issue with your setup/network.

ron329: Thanks for the diagnostic report and the details of your troubleshooting so far. In order to respect your time, I'd recommend giving our support technicians a call to troubleshoot in real time. They can set up a remote session and get a closer look into the cause of the access denied error. Thanks again for your patience.
ron329, I'd recommend that you follow Keith N's instructions in the post before yours, and give their support technicians a call.

Same problem here too.. Windows 10, disabled firewall, checked all permissions and sharing and all is in order. Verified SMBv1 is enabled. Just happened out of the blue. Submitted diagnostics, confirmation number 8461021. Keep getting access is denied error.. HELP
Hi there, poncho. Thanks for posting. If you are still having problems accessing your music library, I'd suggest giving our support technicians a call to troubleshoot in real time. They are able to set up a remote session and get a closer look at how Sonos is linked to your music library.

Thanks!
So I've had this problem on Mac for years. The only solution I've found is to restart the Mac networking service. either reboot, or from Terminal-
prompt: ifconfig en0 down
prompt: ifconfig en0 up
I have this problem, does anyone know of a fix? I have so many problems w/ Sonos flaking out, at this point, wouldn't recommend them 😞
I still have the same problem after trying all the suggested fixes. Luckily my wife is still talking to me, but we both think Sonos is a complete pile of junk. I'm going to revert to an ipod dock as totally fed up with trying to fix this stupid system!!!

Whoops! Looks like I spoke too soon. All the tracks (from My library) show up in the Sonos controller now but won't play. "unable to contact server (computer name)" or something similar. So I disabled the firewall and Hey Presto! Works perfectly. So it would seem that the firewall must be off to either load or play songs from the library.

I have been wrestling with this problem ever since I got mu Sonos a few weeks a go. Everything else works perfectly (Pandora etc), the controller on my computer or phone work perfectly but I could not get access to my iTunes library on my computer. "Computer (name) not found" kept coming up. I went into the control panel >security centre and disabled the firewall and Voila! It loaded the library in a few moments. I am on a Windows XP laptop. Hope this helps. Richard
It worked fine before the lastest update by the way.
got same problem, sonos cant find computer "macbook" Not happy.
I don't know what to say in response. Since first posting my frustrations here, I have "fixed" the problem but have no idea how. It appears to have been while messing around - changing this - changing that. I can't even recall what I did change. I do share everyone's frustrations here. I have no faith that my system will remain "fixed".
I cannot access my iTunes library. I get the same error as others I.e. the computer xx cannot be found Is there a fix for this yet?
I have the same problem - diagnostic submitted - 3047318
Ok in the end we contacted the company who fitted all our sonos stuff after months of trying on my own to fix it! If there has been a power cut at any time ie storms etc it can cause the connections to only go to default. Therefore not accessing the full misic library. Inspire who fitted mine took the box away rebooted it and hey presto I now have h full access to my music library and a whole lot more. It can also be a lost connection don't ask why they just wear out Apparently!
Same problem, firewall is fine, computer name has been shortened and contains no special characters, and still get the error message that my mac can't be found. Diagnostic #: 3038051 Any help totally appreciated.

I am having this problem as well, and I am using a Windows 7 PC. I have changed the name of the PC and updated my firewall settings. Still no luck.
Hello Michael, What is the error message that you receive when attempting to add the music library? Could you try adding the music once again and submit a diagnostic of your system after receiving the error message once again? You can find instructions on how to submit a diagnostic here: https://sonos.custhelp.com/app/answers/detail/a_id/142.

I am having exactly the same problem and am at my wits end. Having persuaded my wife that she could listen to all our music in one place and having thrown our 15 yr old CD system out, I'm looking pretty stupid. What a nightmare... the error message I get is The computer "(null)" cannot be found, Help please before divorce proceedings commence
Scott: Nice of you to respond to those of us who are having this problem. Just as an FYI to you, Sonos worked with me to change the computer name twice (even though it was fewer than 15 characters to begin with), and the problem nonetheless persists. Please see my comment of about 5 days ago on information I've gleaned over time vis-a-vis this problem. It appears to be systemic and may be specific to Sonos interface with Mac products. (FYI, I am going to have another support session with a level 2 tech upon my return from traveling, and we'll see what transpires, but I pass this along for troubleshooting purposes in the meantime, as the problem does seem to be systemic, not individual.)

Hello, The network name that Sonos is finding for your computer, "(null)," is most likely not matching what your computers name is under Sharing. To fix this problem you will need to rename the computer by clicking on the Apple icon > System Preferences > Sharing > Computer Name. Type a computer name that is 15 characters or less with no spaces or punctuation. Once you have made the change you will need to restart your computer. After the restart try to add your music library to Sonos again by going to Manage > Music Library Settings > Click the "+" icon. If you receive an error message please submit a diagnostic. You can find instructions on how to submit a diagnostic here: https://sonos.custhelp.com/app/answers/detail/a_id/142.

I've had numerous calls with Sonos over the last two months, and what is emerging is that there is a problem in the sonos interface with Mac products overall. I'd be interested to know if those who are writing here are on Macs or PCs. My problems started to arise when I migrated from a PC to a Mac. The last tech support person with whom I spoke said directly that the SBS form of file sharing that Sonos uses does not interact smoothly with Mac products, but "hangs up," so that, if you are trying to use the sonos controller on an iPad or iPhone, it may not work. He had a workaround for this (turn off file sharing on the PC, wait a bit, turn it on again), and it seems to work, but of course this defeats the point of using the iPad or iPhone controller, and doesn't at all address the underlying problem of trying to play directly from the Mac computer. I urge everyone to raise this if you call tech support, as it appears this should not be treated as an individual problem specific to each of us as users, but rather is a wider problem that needs a systemic fix.
